MACHINE FOR SETTING L ACIING STUDS OR HOOKS.

EPECIFICATION forming part of Letters Patent No. 356,302, dated January l8, 1887.

6. Serial No. 219,277. (No mtdel.)

To all whom it may concern:

Be it known that I, WILLIAM CLAXTON BRAY, of Newton, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Machines for Setting Shoe-Lace Studs or I-Iooks,of which the following, taken in connection with theacoompanying drawings, is a specification.

My invention relates to the setting-tools of a machine for setting shoe-lace hooks; and it consists in certain novel features of construction, arrangement, and combination of parts, which will be readily understood by reference to the description of the drawings and to the claims to be hereinafter given.

Figure 1 of the drawings-is a front elevation of the setting-tools with a portion of the bed of the machine cut in section. Fig. 2 isa side elevation of the reciprocating setting-plunger, with a small portion of the raceway contiguous thereto in section. Fig. 3 is a rear elevation of the same plunger. Fig. 4 is a plan of said plunger and a small section of the raceway contiguous thereto. Fig. 5 is a plan of said plunger with the end plate removed. Fig. 6 is a vertical section of the upper portion of 7 is a horizontal section on line y 'g on Figs. 2 and 3; and Fig. 8 is a side elevation, showing the setting-tools in position after setting a hook.

My present invention is an improvement upon the machine described in the Letters Patent No. 277,985, granted to me May 22, 1883, in which the setting-plunger was so formed that a lacing stud or hook received in the pocket or support therefor formed in the upper end of said plunger could not be removed therefrom atterbeing setin the materiahexcept by a backward movement of the material. This has been found to be objectionable, on account of the loss of time occasionedby the necessity of moving the material backward and then to the right, in order to place the mate rial in the proper position for setting the next hook. This was especially objectionable in the case of power-machines, and was due to the fact that the cap-plate which entered and filled the space between the outer head and the basecollar of the stud or hook when the same was placed in position thereon for setting necessarily had cut in its rear edge a notch or slot to receive the neck of the stud or hook, the

sides of which slot formed continuations of the sides of the raceway along which the studs or hooks were fed to the setting-tools, for the purpose of insuring the properpresentation of the hook or stud to the action of the setting-tools.

The object of my presentinvention is, while retaining the same continuity of the sides of the 'guideway to the point of deposit of the hook or stud between the setting-tools, to enaable the hook or stud to be removed from the tool after beingset-and the material to be placed in position for setting the next hook by a single movement thereof toward the right.

In the drawings, a is the stationary setting tool or anvil set in the spindle b, adjustably mounted in the head A of the goose-neck of the machine, said anvil being provided with the central teat or point, 0, to serve the double purpose of registering the material by entering the hole punched therein and entering the tubular shank of the stud or hook and turning its end outward as it is being set.

B is the main body of the vertieally-reciprocating setting-plunger fitted to a bearing in the nose of the base of the machine, so as to be movable vertically therein by means of a toggle connected to its lower end, as illustrated in said prior patent, or in any other well-known way. The plunger B has a dovetailed groove, e, planed in one side thereof, a portion of one wall of which,at the upper end, is cut away to the bottom of said groove. as shown in Figs. 2, 3, and 5. A bar, 7", is fitted to said groove 0, so as to be movable endwise therein, and has a portion of its length at its upper end made of a width and shape to fill the cut-away place in the plunger B, said widened portion of said bar, however, being somewhat shorter than the cut-away place in said plunger, so as to permit a movement of said bar toward the lower end of the plunger. The upper end of the plungerB has formed therein the recess or channel 9, extending from the side of said plunger, against which the end ofthe raceway abutsto a point beyond the center of said plunger a distance equal to one-half the diameter of the outer head of the stud or hook to be set, said recess or channel being of a width and depth at least equal to the diameter and thickness of the outer head of said stud or hook, and a plate, h, having a thickness equal to the distance between the outer head and the base-collar of said stud or hook, is secured to said upper end of the plunger by the screw 13 and pin The plate It is provided with a central orifice, h, to permit the passage of the teat or point 0 of the anvil a when the settingtools are brought together in the act of setting the stud or hook. The plate h is in the form of a segment of a disk, a portion of the disk being cut away to form the two straight-edge surfaces k and h, at right angles to each other, the former coinciding with and forming an extension of the inner edge of the guide-platej of the raceway G, and the latter being located at the rear of theaxis of the plunger a distance equal to the distance from the center of the head of the hook or stud to the inner face of the neck thereof, as shown in Fig. 4. The plunger B has formed therein the recess is, in which is placed the spring Z and the disk of rawhide m, arranged to bear against the inner face of the bar f and press it outward to create friction between said plunger and bar, so that said bar and plunger will move together in either direction until the motion of the bar f is arrested by. the pin a, set in the nose of the base of the machine, the inner end of which pin enters the slot 0, formed in said bar, as shown in Figs. 1, 2, and 3. The barf has its upper end so formed that when the portion which is directly beneath the plate It is in 0011- tact with the under surface thereof that portion, f, of said bar which is between the edge h of said plate and the end of the raceway 0 extends upward to a. level with the upper surface of the plate 71, as shown in Figs. 2 and 3. The inner face of the bar f has cut therein just below the plate h the groovef, to permit the passage of the head of the stud or book, while that portion of said face above said groove coincides with and forms an extension of the inner edge of the guide-plate j of the raceway 0 when said plunger is in its lowest position, as shown in Figs. 2, 3, and 4.

The operation of my invent-ion is as follows: The plunger 13 being in its lowest position, a hook is fed along the raceway to a position on the plate h, with the center of the tubular shank of the hook directly over the center or axis of the plunger B, with its head beneath the plate It and the inner face of the neck in contact with the edge 715 of said plate. The article in which the hook is to be set, having holes punched therein to receive thehooks, is placed against the lower end of the anvil a, with the teat or point 0 entering one of said holes, when the plunger B is moved upward, carrying with it the barf and the hook to be set. XVhen the tubular shank of the hook has come in contact with the anvil and is firmly held between it and the plate It, so that it cannot be displaced, the lower end of the slot 0 in the barf comes in contact with the pin a, and the upward movement of said bar is arrested, while the upward movement of the plunger continues until the hook is firmly clinched to the material, when the bar f will bear the relation to the plunger B and the plate It shown in Fig. 8. WVhenthe plunger commences to descend, after setting the hook, it carries with it the barf in the relative position shown in Fig. 8, until the upper end of the sloto comes in contact with the pin n and prevents the further downward movement of said bar, the plunger continuing to move downward until the highest part of the barfis on a level with the upper surface of the plate h, as shown in Figs. 2 and 3. As soon as the plunger has descended sufficiently far to withdraw theteat or point cfrom the set-hook, and before the end of the slot 0 comesin contact with the pin a, the set-hook may be withdrawn from the setting-plunger by movingitin aright line in a direction at right angles to the raceway C, and by the same movement, combined with a slight upward movement of the material ,the material may be placed in position with the pointc in thenext hole preparatory to setting the next stud or hook.

\Vhat I claim as new, and desire to secure by Letters Patent of the United States, is-

l. The plunger B, provided with the dovetailed groove eand the recess or channel 9, in combination with the barf, provided with the upward extension f, the groove f, and the slot 0, the plate h, provided with the angular notch h h, and the stoppin a, all constructed, arranged, and operating substantially as described.

2. The combination, with a fixed anvil and astationary raceway or channel through which studs or hooks may be fed to a position for setting, of a reciprocating plunger provided with a recess or channel to receive the head of a lacinghook, the plate h, provided with the angular notch h h, the barf, provided with the groove f and the extension f and fitted to a longitudinal bearing in said plunger, and movable therewith in either direction by friction, and a stop for limiting the movement of said bar in either direction to a distance less than the movement of the plunger, substantial] y as described.

In testimony whereof I have signed my name to this specificatiomin the presence of two subscribing witnesses,on this 16th day of November,A. D. 1886.
